LEWIS STEIN, OF NEV YORK, N. Y.

ELASTIC STRAP.

SPECIFICATION forming part of Letters Patent No. 400,266, dated March 26, 1889.

Application filed November 15, 1888. Serial No. 290,870. (No model.)

To aZZ whom it may concern.-

Be it known that I, LEWIS STEIN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Elastic Adj Listing-Straps, of which the following is a specification.

My invention relates especially to that class of elastic adjusting-straps in which the desired elasticity is afforded by means of spiral springs; and it consists of the novel features of construction, hereinafter described, for producing a cheap, strong, and durable connection of the spiral springs with their attaching devices.

In the accompanying drawings, Figure 1 represents a front view, partly in section, of an adj Listing-strap embodying my invention, the attaching devices being buckles. Fig. 2 represents a side view, partly in section, thereof. Fig. 3.represents a cross-section thereof. Fig. 4 represents a front view corresponding to Fig. 1, the attaching devices being plain links.

Similar letters of reference indicate similar parts.

The letter A indicates the spiral springs, which may be round, oval, or of any other selected shape in cross-section, and may or may not be covered with braid or similar material. The free ends of each of said springs A are bent substantially at right angles to form coils B, projecting longitudinally from the springs, and into said end coils of the series of springs, at the opposite ends thereof, are inserted wire links C, each of which is formed with a plain straight bar or member, 0, to receive the end coils, so that the springs are connected to said links by means of the end coils engaging said plain members of the links, the springs lying in a corresponding plane to each other. To permit the introduction of either link 0 in said end coils, B, of the springs, it is left open, and in the example shown in Figs. 1 and 2 the free ends of the link-wire are arranged to form the pin-tongues of abuckle, of which 0 is the frame, while in the example shown in Fig. 4 said ends of the link-wire are simplybrought together, as at 0 said link in either event being a medium for attaching the elastic strap to the desired article, as to the back-band of a vest or trousers or to a trousers-Suspender. At each end of the series of spiral springs A is a housing, D, of sheet metal, which is folded in a proper manner to embrace said member 0 of either link, together with the end coils, B, thereupon, as at D, and also to embrace the adjacent end portions of the springs, as at D so that these housings are connected to the links by engaging said bar, while they conceal and protect the ends of the springs. By this construction, therefore, a direct connection is effected of both the springs A'and their end-protecting housings D, with the strap-attaching links 0, producing a very strong and durable strap with economy of labor and material and at a comparatively low cost of manufacture.

I am aware that a strap-link has been constructed in one instance with hooks, as shown in Letters Patent No. 176,263, dated April 18, 1876, and in another instance with eyes, the latter to receive a pin, as shown in Letters Patent No. 188,330, dated March 13, 1877, for connecting the link with spiral springs, said hooks, as well as the pin, engaging with coils of the springs at a point inward from the ends of the springs; also that a sheetmetal housing has been constructed with barbs or prongs for connecting it with spiral openings, as shown in Letters Patent No. 376,727, dated August 2, 1887; and such is not within the scope of my invention, which differs therefrom in that not only the spiral springs, but also the housings, are connected with a plain portion of the link, the springs by means of their end coils and the housings by means of a suitable fold, as described, one important advantage thus gained being that the full elasticity of all the coils of the springs is utilized, whereas in the old constructions named a portion of such elasticity is lost, due to the fact that a number of coils at both ends of the springs are rendered inoperative, and another advantage being that the housings are in a fixed position at the ends of the springs by engaging the bars of the links.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

liran elastic adj Listing-strap for garments, a series of spiral springs, A, each having its free ends formed into coils B at right angles and the housings With said links, substantial ly as shown and described, for the purpose set [0 forth.
